Beamforming
Sound data is overlaid onto the camera image with selectable resolution from 80x60 to 640x480 pixels. GPU acceleration supports CUDA and OpenCL workflows.
Microphone array and real-time acoustic imaging software
ViewNoise Acoustic Camera
ViewNoise combines a 64-channel MEMS microphone array, optical camera and GPU-accelerated software to localize, visualize and analyze sound sources in real time or offline.

48 kHz24-bit audio capture
30 HzFull HD video
MA64UB530R6 microphone array and data acquisition controller.
Designed for clear acoustic decisions
ViewNoise turns sound into a visual layer over camera video, helping engineers identify sources, compare frequencies and record synchronized audio-video evidence.
Virtual directional microphone
Listen to a selected point in the scene during live monitoring or playback, with precise sound-source localization at the cursor position.
Virtual HDR microphones
Place up to 63 virtual HDR microphones with a 64-microphone array for advanced source separation in complex noise environments.
Acoustic eraser
Suppress selected sound directions in real time, with support for concurrent suppression of up to 64 sources.
Spectrogram and spectrum
Inspect time-frequency behavior, spectrum views and real-time audio signal displays from physical, directional or virtual HDR microphones.
Recording and playback
Record 64 channels of 24-bit audio at 48 kHz together with video, then review synchronized playback with color, black-and-white or contour video modes.

Realtime and offline analysis
All ViewNoise functionalities are available live and in recorded sessions. Offline mode supports comments and slow motion with an acoustic frame rate up to 24,000 frames per second.
GPU acceleration
Beamforming calculations use CUDA for NVIDIA GPUs and OpenCL for NVIDIA, AMD and Intel GPUs. Minimum recommended theoretical GPU performance is 1.5 TFLOPS.
Video codecs
Recording supports x264 and x265 hardware encoders compatible with Intel, AMD and NVIDIA GPUs, plus CPU-based x264/x265 software encoding options.
Computer requirements
Windows 10/11 64-bit, CPU with 4+ cores, 16 GB RAM, CUDA/OpenCL GPU and SSD storage. A 60-second recording can take up to 1 GB of disk space.
Applications
